Genfleet Therapeutics Inc. has entered the KRAS G12C inhibitor race in the U.S. as it gears up to begin phase III trials of GFH-925 (IBI-351) in patients with refractory metastatic colorectal cancer (CRC) following FDA clearance.
The timing is ripe for a robust biosimilar market in China, given the rapid increase of novel biologics approved to treat cancer and inflammatory diseases in the country over the past decade and the looming patent cliffs for several established biologics. As of December, the NMPA had approved more than 20 biosimilars that were developed in China. Most of those referenced just two biologics – Roche AG’s cancer drug Avastin (bevacizumab) and Abbvie Inc.’s immunology drug Humira (adalimumab). In 2022, the oncology and immunology biosimilar market in China garnered sales of about $2 billion, according to Clarivate estimates. To reach their full potential in China though, biosimilars must win over prescribers and patients.
Follow-on biologic makers in China have been working to capitalize on looming patent cliffs of blockbuster biologics. Advancing biosimilars of denosumab (Prolia/Xgeva; Amgen Inc.) and semaglutide are the latest examples.
Sino Biopharmaceutical Ltd. and Boehringer Ingelheim International GmbH are partnering to develop innovative cancer therapies in mainland China. They will jointly develop and commercialize three clinical Boehringer assets, including brigimadlin, zongertinib, BI-764532, and other unnamed early stage assets.
Medicxi has made its first ever investment in China – and its biggest single commitment to date – putting $40 million into D3 Bio Inc. The investment by the London-based venture capital firm will accelerate development of D3’s lead program D3S-001, a second generation KRAS G12C inhibitor, which is in phase II development in advanced solid tumors.
After reviewing data from its phase II trial of farnesoid X receptor agonist ASC-42 in primary biliary cholangitis, Ascletis Pharma Inc. said it was quitting development of the molecule in all indications.
Biosimilar competition to Amgen Inc.’s denosumab (Prolia/Xgeva) is rising globally, with Mabwell (Shanghai) Bioscience Co. Ltd. gaining the latest China NMPA approval of Maiweijian (TK-006) on April 8. Mabwell’s wholly owned subsidiary, Jiangsu T-mab Biopharma Co. Ltd., gained NMPA clearance of Maiweijian (120 mg) as the first denosumab biosimilar for the indications of U.S.-licensed Xgeva for bone-related diseases.
China’s Visen Pharmaceuticals (Shanghai) Co. Ltd. is targeting an IPO on the Hong Kong stock exchange with three rare endocrine disease therapies licensed-in from Denmark’s Ascendis Pharma A/S, including U.S. FDA-approved Skytrofa (lonapegsomatropin).
Beijing- and Shanghai-based Sperogenix Therapeutics Ltd. said that China’s regulatory agency accepted the NDA filing and granted priority review of Agamree (vamorolone) for Duchenne muscular dystrophy on March 26.
South Korean biopharma Aribio Co. Ltd. signed a $770 million deal to sign off exclusive rights to its early Alzheimer’s disease drug, AR-1001 (mirodenafil), in China. The exclusive deal for marketing rights will total about ¥5.59 billion (US$770 million), which includes a non-refundable up-front payment of ₩120 billion (US$90 million) and potential milestone payments, along with royalties.
